- added portasm support for adding .section .note.GNU-stack "hints" marking generated .o files from assembly files as not needing an executable stack
* needed to be done manually in assembly files, in contrast to C translation units where gcc adds such hints automatically
* this is for security, and better/easier integration of dyncall into other projects and builds, as dyncall doesn't need an executable stack
* thanks to Thorsten Behrens for bringing this up to our intention and providing a first analysis
* currently only done on Linux, but will be added across other platforms (where applicable) after some testing
